To all whom it may concern:

Be it known that I, CARL H. CARLSON, a citizen of the United States, anda resident of Iron Mountain, in the county of Dickinson, State ofMichigan, have invented certain new and useful Improvements in Butterand Lard Cutters, of which the tollowing is a specication.

My invention is an improvement in butter and lard cutters, and consistsin certain novel constructions and combinations of parts hereinafterdescribed and claimed.

The object of the invention is to provide a device of thecharacterspecitied, especially adapted to cut out and remove a shapedpat of butter or lard from a iirkin or other receptacle, and which isprovided with means for ejecting the pat from the device without thenecessity of touching it with the hands or with any other tool.

Referring to the drawings forming a part hereof: Figure 1 is a centrallongitudinal section of the improved cutter; Fig. 2 is a similar view ofa portion of the handle at right angles to Fig. 1; Fig. 3 is a sectionon the line 3 3 of Fig. l looking in the direction of the arrow; Fig. 4is a section on the line 4 4 of Fig. 2; Fig. 5 is a perspective view ofa portion of the handle with .the parts separated; Fig. 6. is a sideview of a portion of the handle; Fig. 7 is a diagrammatic side viewshowing the method of use; Fig. 8 is a similar View showing a portion ofthe material cut out and in the act of being removed; and Fig; 9 is asimilar view with the portion ready to be removed.

The embodiment of the invention shown in the drawings consists of aframe comprising a yoke-shaped body 1 provided with oppositely arrangedsubstantially parallel arms 2-3 and with a tubular extension projectingfrom the center of the body portion in the opposite direction from thearms. Near its upper end the extension 1s prot vided with oppositelyarranged longitudinal slots 5, through which extend the ends of a lingerpiece 6, which is secured by its center to the stem 7 of a plunger 8,which is movable between the arms 3 of the yoke, the stem sliding in thetubular extension.

The end of the stem 7 is provided with an annular groove 9, which isengaged by inwardly extending lugs 10 on the arms 12 of a sleeve 11, andthe finger piece 6 is arranged between t-he end of the stem and the bodyof the sleeve as showniin Figs. 1, 2 and 5;- A sleeve 13 encircles theextension at the slots 5, the sleeve being provided with slots 14registering with the slots 5 and with lateral flanges 15 havingregistering openings 16 through which is passed a bolt 17 for clampingthe sleeve on the extension.

The slots 14 are of lesser width than the slots 5, and each is providedat its lower end with a lateral extension 18 havingva 'lip 19 at thecorner formed byv the junction oi the slot with the lateral. portion,and the said lateral extensions extend in opposite directions, so thatby partially rotating the linger piece it may be locked in the lateralextension, the lips preventing its disengagement.

Above the slots 5 the extension is provided with a diaphragm 20 having acentral opening which registers with openings through the sleeve 11 andthe stem '7, and a rod 21 is slidable in the stem and through theopenings. The rod is provided on its lower end with a cross plate 22 andon its upper end with a nut 23 threaded thereon, and between the nut andthe diaphragm a spring 24 is arranged for normally retaining the plateagainst the plunger. K

The free end of the tubular extension 7 is provided with a handle 25,and the lower ends of the arms 3 are connected by a cross bar 26, uponeach end of which is journaled a cutter. Each cutter consists of asubstantially triangular plate 27 provided on one side edge with spacedbearings 28 in which the rod is loosely received.

In operation, the cutter is inserted in the rkin 29, containing thematerial 30 to be out, with the parts in the position shown in Figs. land 7. As the arms enter the material the cutters take the ositionshownvin Fig. 7, since in this position they offer the least resistance.When the cutter is inserted deep enough to remove a pat of the desiredsize, it is rotated by means of the handle 25.

lVhen the cutter is rotated, the cutters take' the position shown inFig. 8, for the reason above stated, and in their movement revolvingabout an axis coinciding with the longitudinal center of the tubularextension, the pat is separated at its bottom by the cutters, and on itssides by the arms 8, which have sharp edges 31, as indicated in Fig. 3.The pat is now completely separated from the remaining material, asshown in Fig. 8, and

l portion is removed from the rkin, Vit being understood that during theabove described opera-` tion the plunger 8V is locked in position by theengagement of the linger piece with the lateral extensions of the slots,while the s ring, beingunder compression, holds the p ate firmly,against the plunger. The cutter with `the pat in lace is held above therece tacle in which 1t is to be placed, and the ger piece is disengagedfrom the lateral extensions of the slots, and moved upwardly into theposition shown in Fig. 9. The plate as shown4 in Fig. 9 is curved andarranged with its convex face downward, and as soon as it is releasedfrom the pressure of the plate it resumes its curved condition, thusfreeing the pat from the plunger and from itself, except at the centralportion thereof.

As will be evident from an inspection of Figs. 1 and 7 to 9, inclusive,the arms 3 of the yoke l incline inwardly toward their free end, so thatwhen the pat follows the plunger in its upward movement it enters thewidest prart of the frame, and is easily disenggged om the arms,slipping out at either s1 e.

The diametrical division of the pat made by the rod 26 may bepractically obliterated before removing the pat from the firkin by adownward pressure on the plunger, the arms 3 and cutters 27 also aiding,by compactil'ig the lpat, or the cut ma be disregarded, in w ich casethe pat wi l be in two semicylindrical sections.

The improved cutters may be easily separated for cleaning or otherpurposes,by slipping out the linger pieceA through the slots andunscrewing the nut 23, the sleeve 13 being first loosened and removed.The plate and rod may now be withdrawn. This procedure is indicated inFig. 5.

The depth of the insertion of the cutter may be regulated by means ofthe sleeve A13, which may be adjusted on the extension, and when securedin adjusted position by the set screw 17 the plunger, wil limit thedownward movement of the cutter, and the plunger is locked in fixedposition by the engagement of the linger piece with the sleeve.

The nut 23 is moved out of the end of the extension by the spring 24,and into such position that it may be gras ed to turn the rod and thecutter 22 a hal turn, thus entirely releasing the pat from the plunger.
